returns an answer signal. Then the host receives the answer signal and begins to receive 40-
bit humiture data (8-bit humidity i 8-bit humidity d 8-bit temperature integer
+ 8-bit temperature d 8-bit checksum). For more information, please refer to DHT11
datasheet.
Experimental Procedures
Step 1:
Build the circuit
Humiture Sensor Module SunFounder Uno
S --------------------------------------- D4
- ---------------------------------------- GND
+ --------------------------------------- 5V
LCD1602 connection:
connect pin RS to digital pin 5; R/W to GND; E to digital pin 6; D4~D7 to
digital pin 9 to 12; VSS to GND; VDD to 5V; A to 3.3V; K to GND
Potentiometer connection
: Connect the middle pin to VO of LCD1602 and any other pin to
GND
Step 2:
Program (Please refer to the example code in
LEARN -> Get Tutorial
on our
website
)
Step 3:
Compile
Step 4:
Upload the sketch to SunFounder Uno
Now, you can see the value of the current humidity and temperature displayed on the LCD.
